摘要
近年来,锑基Ⅱ类超晶格红外探测器受到特别的关注,主要原因在于:锑化物Ⅱ类超晶格材料可能具有与碲镉汞相当的红外材料特性。根据Ⅱ类超晶格材料的基本特性、能带结构与电子空穴物理分离机理、美国3个主力联合研究团队的攻关现状,对Ⅱ类超晶格材料、器件的难点与前景进行分析。
Recently,the Antimony based type Ⅱ superlattice detectors have attracted much attention,for it is believed that this kind of material may show similar properties to the state-of-the-art HgCdTe.The principles,status and prospect of the type Ⅱ superlattice detectors are reviewed based on the material band structure,special separation features for electrons and holes in the superlattices,and the research results from the three major American research teams.
